Abstract

The invention relates to a method for detecting a partial discharge position. The method comprises the following steps: acquiring a discharge signal and a coordinate position which are acquired by an ultrahigh-frequency partial discharge sensor in real time in a moving process; according to the amplitude value of the discharge signal, determining the pipeline position where the discharge signal is located; and determining a discharge position on the pipeline position according to the discharge signal and the coordinate position. The method can enlarge the acquisition range of the sensor, simplify the calculation method and improve the precision of the discharge position.

Description

technical field [0001] The present application relates to the field of substations, in particular to a method and system for detecting the position and amount of partial discharge. Background technique [0002] With the development of the Internet and the continuous improvement of substation automation technology, the efficiency requirements of power grid companies are getting higher and higher, and the unattended mode has been fully promoted in substations. [0003] At the substation site, the discharge signal collected by the on-site UHF partial discharge sensor can be remotely received to analyze the discharge location. see figure 1 ,Such as figure 1 As shown, there are a lot of pipes surrounding the pot insulator at the substation site to shield the discharge of the pot insulator, and the connection between the pipes is connected by a flange, and the discharge signal of the pot insulator can be detected at the flange connection, so The UHF partial discharge sensor is ...
